So I "pulled the trigger" on one of these. Some of the reviews stated that in some cases, the meals weren't sealed? or there was a "dust" inside. That said, just wondering if that is a past problem? Also, are the ones being sold now in a round 6 gallon pail(saw some in a square pail)? I hope so, cause I bought a couple of Gamma Lids, LOL Thanks Wanna kill these ads? We can help!
